Benefits of technology

The patent aims to improve the size, construction costs, and efficiency of a rotating valve and heat pump.

Problems solved by technology

Only radially oriented flow openings in the region of the alternating interconnection are known from the conventional art, which results in complex approaches, at least with regard to the installation space, for example double-walled cylinders having radially oriented openings disposed therein which are offset from each other.

Embodiment Construction

[0092]FIG. 1 shows a heat pump in which a plurality of, in the present case, twelve hollow elements 1 are disposed parallel to each other in the manner of a stack. The stack of hollow elements 1 is detachably connected via tension members 2 to form a structural unit.

[0093]Each of hollow elements 1 has a first zone A in the form of an adsorption / desorption zone and a second zone B in the form of an evaporation / condensation zone. First zone A is penetrated by a first flow channel 3 of a circulating first fluid which is transported by a pump (not illustrated) for each of hollow elements 1, and second zone B is penetrated by a second flow channel 4 of a second fluid, which in the present example is different from the first fluid, but does not necessarily have to be so, for each of hollow elements 1. Each of flow channels 3, 4 has end-face connections 3a, 3b which are diametrically opposed to each other and which each serve as inlets or outlets for the fluid flowing through flow channels...

Abstract

A rotating valve includes an inlet region, an outlet region, and a switching region having a switching member that can be rotated about an axis. In a first position of the switching member the plurality of inlets are connected to the plurality of outlets in a first association, and in a second position of the switching member the plurality of inlets are connected to the plurality of outlets in a second association. The switching member has a plurality of openings through which the fluid flows flow axially in the direction of the rotation axis and are moved together with the switching member. The openings alternately cover a plurality of stationary, axially directed openings in the course of the rotation of the switching member. Different associations of the inlets with the outlets are carried out by the alternating covering of the axially directed openings.

Description

[0001]This nonprovisional application is a continuation of International Application No. PCT / EP2010 / 061470, which was filed on Aug. 6, 2010, and which claims priority to German Patent Application No. DE 10 2009 036 544.3, which was filed in Germany on Aug. 7, 2009, and which are both herein incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to a rotating valve and to a heat pump.[0004]2. Description of the Background Art[0005]The use of rotating valves is known, in principle, for the alternating interconnection of a plurality of fluid flows for driving a heat pump which has a large number of particular thermodynamically active flow channels.[0006]WO 2007 / 068481 A1, which corresponds to US 2009 / 0000327, which is incorporated herein by reference, describes a heat pump which includes a permanently interconnected stack of plate-type hollow elements, the hollow elements comprising adsorber / desorber regions and each hollow eleme...
